We only interact with the very surface of the Earth, called the crust. So what else is down there? What is the composition of the Earth? How many layers are there, and how do they differ? What is the mantle, and how does it convect? What...

If you have ever torn up a piece of paper or seen ice melt, then you have witnessed physical changes. This fascinating program helps students understand some of the different ways matter changes physically. Vivid animations also...

Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about bioling, melting and heating different substances!

This video explains the relationship between energy and changes of states in matter. It discusses the different changes of state, such as melting, boiling, and condensing, and the fixed temperatures at which they occur. The concept of...

It explains separation of solid-solid mixture by using two methods, namely sublimation and evaporation.

This video is a lecture on specific latent heat, which looks at the energy absorbed or emitted by a substance as it changes states (solid, liquid, or gas). The lecture discusses two equations that can be used to calculate the amount of...

What are the characteristics of water? Explain the water cycle?<br/>
Properties Of Water, Part 1

Matter. It is all around us. Everything on Earth is made of matter. Learning about the different properties of matter will allow students to understand how environmental and human factors affect the changing world we live in. By viewing...

This live-action video program is about the word Density. The program is designed to reinforce and support a student's comprehension and retention of the word Density through use of video footage, photographs, diagrams and colorful,...

From the Hindu festival of Dessehra to a kitchen in Chinatown, we bring you five demonstrations of non-reversible changes resulting in new materials, for use with students in the classroom. Non-reversible changes result in the formation...

This question has been bugging me for about 20 years. And, ultimately, it still bugs me...

This live-action video program is about the term change of state. The program is designed to reinforce and support a student's comprehension and retention of the term change of state through use of video footage, photographs, diagrams...

In this video, the teacher explains how to represent three-dimensional figures in two dimensions using nets. They define dimensions and give examples of one-dimensional, two-dimensional, and three-dimensional figures. They also...

In this video, you will learn how to find the surface area of triangular prisms by calculating the area of the faces that make up the figure. The video provides an example problem and offers helpful tips and shortcuts for solving similar...

What the heck is dry ice and why is it so spooky? Learn this and more when we investigate phase changes and phase diagrams!

An exothermic reaction gives off energy to the surroundings; like a fire giving off heat. An endothermic reaction takes in energy from the surroundings; like a snowman melting. Exothermic reactions transfer energy to the surroundings,...

Learn the basics about plasma - the fourth state of matter, when learning about properties of matter. When ice is sufficiently heated, it melts to form water. It has therefore undergone a change of state – from a solid to a liquid....

When you hear the roar of traffic, the bark of a dog, or your teacher's voice, you are experiencing sound. This program uses colorful animations to explore important characteristics of sound, including intensity, loudness, pitch, and...

Many of the things we eat and enjoy are grown in soil. This engaging program explores the soil and rocks importance of soil while taking a look at how soil is formed. Different types of soil and their characteristics are explored.

In this video, the teacher explains how to determine the volume of a prism by multiplying the area of the base by the height. They provide examples and guide students through the process step by step.

In this video, the teacher explains how to determine whether to measure in square units (area), surface area, or cubic units (volume) in different situations. They provide examples and clarify that area is used for 2D objects, surface...

This video explains the history of the theory of continental drift and how it eventually led to the development of the theory of plate tectonics. The video also explains the concept of tectonic plates, how they ride on Earth's surface,...

When a substance changes its state, heat energy is involved. This energy is used not to heat up the substance, but to separate the molecules from each other. This is known as specific latent heat. Specific latent heat is defined as the...

In this video you are going to learn how we used earthquakes to look deep into the earth. The study of S and P waves helped us understand that the Earth has a layered structure, with a solid inner core surrounded by an outer liquid core.
